Abstract: FIELD: medicine, particularly, medical endoscopes; may be used in detection of early pathology of internal organs. SUBSTANCE: infrared endoscope has endoscopic probe with illuminator attached to one end of probe and optical infrared converter attached to the probe other end. Optical infrared converter is connected to unit of indication and analysis of converter. Optical infrared converter is in the form of microcircuit with optical inlet; and indication and analysis unit is in the form of board or separate unit. Illuminator possesses radiation characteristics allowing formation of three monochromatic rays with at least one of which being in infrared spectrum. Method of detection of early pathology of internal organs is realized as follows. Introduced into patient place of expected pathology is infrared endoscope (in the form of gastro-, broncho-, laparo- or cystoscope or others) and examined tissue is radiated for 1/30 s with successively supplied three monochromatic rays of different spectrums. One of such rays is ray with wave length found in infrared spectrum; the second ray, in infrared or visible region of spectrum, the third ray, in infrared, visible or ultraviolet region of spectrum. Thus, three monochromatic pictures are obtained which are superposed on one another to form colored picture of image of pathology boundaries. Pathology boundaries are measured. The invention may found wide application in criminalistics for detection of counterfeits of artistic values, in particular, pictures, prints, sketches, etc, and also in aviation for detection of defects in the form of fatigue microcracks and cavities in nozzle vanes and rotor blades of turbines of gas turbine engines during maintenance diagnostics of aircraft power plants and engines, etc. EFFECT: higher confidence of detection of early stage of internal organ pathology. 2 cl, 1 dwg

Granted: 1997-06-20
Abstract: FIELD: sewage purification practice at small- and large-scale purification and after-purification plants for treating effluents of domestic and industrial origin. SUBSTANCE: proposed method uses conventional procedure of treating effluents with activated sludge in aerotanks and secondary settling tanks, followed by tertiary treatment (after-purification) by contacting water with immersed higher aquatic plant in flow-through channel. Inventive novelty of proposed method resides in using aquatic plant Najas microdon. Sewage flow rate in flow-through channel is set in such manner that 1 kg of plant weight would be present per about 2.4 g of nitrogen-containing substances and per 0.5 g of phosphates daily. Water temperature in channel is maintained over range +12 - +20 C, 15% by weight of Najas microdon biomass being removed from reaction pool every 20 days.

Ultrasonic oscillations reflected from boundary between liquid and opposite internal surface of tube having deposits are taken, and time t 2  of passage of ultrasonic oscillations is measured. Then time t 3  of ultrasonic oscillation passage from first to second ultrasonic transducers is measured, and pipeline flow section is determined by formula: D = [(t 1 +t 2 -2t 3 )c]/2, where D is diameter of pipeline flow section and C is speed of ultrasound in liquid. Measurements can be performed with pipeline filled with water.
